Specification of Letters Patent. i Patented Aug'. 2S, 1917.,

Application led March 15, 1916. Serial No. 84,302.

To all whom t may concern.'

Be it known that I, ERNEST FLAGG, a citilzen of the United States, and a resident of lates to supports for cementitious materials as used chiefly in building construction. An object of the invention is to provide a simple and inexpensive method of building parti- A further object is to provide a flexible support for the partition which is adapted to be drawn taut or stretched under the weight of the plastic mass applied to allow the anchoring of said partition in said tautened condition.

With the above and other objects in view, the nature of which will more fully appear as` the description proceeds, the invention consists in the combination and arrangement of parts as herein fully described, illustrated and claimed. In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in all the views, and

Figure 1 is a vertical section through a partition in process of construction; and

Fig. 2 is a fragmentary elevation of the partition support `before the cementitious material is applied thereto.

Heretofore, it has been necessary to construct a framework of some kind which formed the skeleton of the partition upon which its strength depended and upon which the plaster or other cementitious material was supported. The comparatively recent introduction of cements of great strength for use in plastering, now makes it possible to build partitions, the strength of which depends upon the material only and which need no framework for strength. The support is-needed simply to hold the plaster until it has time to set. Partitions made of wire lath supported by the light framework of metal studs have been in use for some years, but the cost of the framework is the chief cost of the partition. Moreover, it is a source of weakness, for when such a partition is subjected to severe heat, the iron rods expand and break out the plaster whereever they occur.

` other fasteners,

To obviate the above objections to the framework, I provide a support without a framework. The support proper comprises a fabric 3 made of expanded metal, wire mesh or other suitable material.j One edge of the fabric is secured to hooks or clamps or to a rod 4 of any suitable cross section. This rod is suspended from any suitable hangers secured to the ceiling,`the hangers being provided at the places where the partition is to be formed. In case of fireproof structures, the hangers may extend through the ceiling to engage above the floor a similar rod 4, to which the lower edge of a fabric of a partition above is secured.

Where the hangers 5 do not extend through the ceiling, be driven into, or otherwise connected to, the floor to receive the -rod 4 for the lower edge of the partition; or the fabric may be secured directly to the floor by hooks, staples, or other means. The lower edge of the supportlng fabric is tied to said rod, or the so as to make the fabric suliiclently taut without trying to eliminate the undulations present in such fabrics. '.lfhere is no necessity of tightening the fab. r1c like the wires of a reinforcement or a partition.

To the fabric stretched between the lower and upper supports, cementitious material 7 is applied, preferably from both sides, beginning from about one foot from the Hoor and up to the ceiling. The weight of the cementitious material causes the fabric to hang tight; and if there be any surplus due to the undulation present in the fabric, the fabric will stretch and buckle as shown in Fig. 1. rfhe fabric being flexible and free to swing in a vertical plane allows the partition so formed to plumb. The buckled portion 8 of the partition at the lower fastening can then be tightened, or, if desired, the excess cut away and the lower edge again secured to the fastening. After eliminating the buckled-up portion of the support 8, the cementitious material is applied to extend to the lioor, thereby completing the partition. The fabric stretched by weight of the plastic material affords all the support needed for the cementitious material 7 while it is wet; and it will also act as a reinforcement for imparting additional strength to the material supported.

The partition so constructed is fireproof in its character, but it may be applicable to suitable supports 6 may v non-fireproof constructions. The partitions are both economical of space and material. They can be set up for less cost than the ordinary wooden stud and lath partitions; and they occupy only about one-third the space of ordinary partitions.

I claim:

1. The method of building cementitious partitions which consists in providing 4 a yielding vertical support between the floor and the ceiling, covering the said support with cementitious material With the exception of the lower part of the sup ort near the iioor, eliminating anyA slac mess or stretch of the support in the exposed part that is caused by the Weight of the cementitious material applied" to the support2 and covering the exposed part with cementitious material to complete the partition.

2. The method ofV building cementitious of the support, and covering partitions which consists in suspending a flexible support between the ceiling and ioor, covering the support With cementitious material, except the lower part of the support at the floor, to allow said support to straighten and plumb under the weight of the cementitious material applied to the support, eliminating the excess of material caused by the Weight from the exposed part i the exposed part of the support with cementitious material to complete the partition.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
